HYDROCARBON-BURNER.

SPEGIFIGATION forming part of Letters Patent No. 667,641, dated February 5, 1901.

Application filed August 7, 1900- Serial No. 26,190. (No model.)

To all whom it may concern:

Be it known that 1, JAMES D. WILLIAMSON, a citizen of Canada, residing at 122 Turk street, in the city and county of San Francisco, in the State of California, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates to improvements in hydrocarbon-burners,and particularly to that class wherein the hydrocarbon is vaporized before combustion.

The burner illustrated herein is destined particularly for operation in the fire-box of cooking stoves or ranges as a substitute for coal or wood.

In the drawings, Figure 1 is a vertical crosssection of the present burner and'the vaporgenerator used therewith, the section of the burner being taken on the plane of the line a" w of Fig. 2. Fig. 2 is a plan View from above of the burner with the top removed. Fig. 3 is a plan view from above below the line 00 as of Fig. 1. Fig. 4 is a vertical crosssection of a portion of the burner, showing the method of introducing the hydrocarbon thereto.

In the description, with reference to the drawings, distinguishing letters of reference will be given to the major parts of the Structure, to which common letters a numeral will be added to distinguish the minor parts of each group.

The retort will be distinguished by letter A, the lid therefor by the letter B, the airchamber by the letter O, the air-mixer-by the letter D, the tie-bolt connecting the various parts together by the letter E, and the vaporgenerator by the letter F.

The burner is particularly adapted to the burning of kerosene and will be described in connection therewith. The oil is introduced into the burner by gravitation through the pipe B, connecting by the passage 13 with the annular channel A of the retort A. The oil is introduced behind the wall A of the channel A, and travels the entire circuit of the channel A before entering the vaporizing-retort A. When starting up with the whole apparatus cold, the oil will not vaporize. Preliminary heating of the retort A is provided for by letting the oil overflow into the cup 0, having the absorbent wick C therein, and lighting it. When the retort A has become su fficiently heated, the oil-feed may be regulated to give the desired amount of flame. Presuming the retort to be sufficiently heated, the oil is fed into the channel A and is converted into a wet vapor in travcling around same to the entrance A to the vaporizing-retort- A, wherein it is converted into a dry vapor and ignited at the exit-holes A. From the exit-holes A the flame travels upward, striking under the overhanging flange A", and is thrown downward and outward thereby. The channel A being situated directly over the apex of the angle formed by the flange A is kept hot. The flame traveling up the side of the retort A keeps it hot 7 and insures the proper vaporizing of the hydrocar'bon.

In placing the burners in the fire-box of a stove or under similar condition the air-chamber O is permitted to rest on the grate-bars, the space between and around the burners being closed by fire-clay in any suitable manner to compel the air drawn into the stove to is created to reach around the oven, as does the coal-flame. These have been found expensive, sooty, and undesirable, whereas I depend on heating all the air passing into the stove with the minimum of flame and no soot.

Burners constructed in accordance with this invention have proved their ability to handle all the hydrocarbons from gasolene to coaloils containing an average proportion of bitumen or base products. It is in handling the lower-grade oils that the generator F is used. This consists of a hollow box or chamber having its inlet F and outlet F near the top. The generator-outlet F is connected to the pipe B close enough to the burner to receive sufiicient heat therefrom to cause the vaporization of the oil before passing into the channel A, leaving the base matter of the oil in the generator F, which may be cleaned by removing the cover F Under ordinary conditions the generator F is unnecessary, the base products being trapped in the bottom of the channel A or in the pocket A below the openings A in the retort A, where such products as sand or other non-combustibles may be removed by removing the lid B.

Any number of these burners may be operated in multiple by connecting the inlets B to a common supply-pipe.

In assembling the parts the tie-bolt E is screwed into the center of the cup C, which is supported within the air-cham ber C by the cross-web E the air-mixer D is placed in p0? sition, the retort A is slipped onto the bolt E, resting on the'bottom of the cup 0, the asbestos packing B is placed in position over the channel A, and the lid B and the other parts are maintained in their relative positions by the nut E on the bolt E, screwed against the lid. In adjusting the lid B'care should be used to adjust the passage 13*, to empty into the channel A, at the extreme end removed from the entry A into the retort A.

Having thus described this invention, it is claimed 1. In a hydrocarbon-burner, the combination of a retort having ignition-holes near its bottom; upwardly-extending,overhanging walls, having an outwardly-extending annular flange near the top thereof; an annular channel situated above the said annular flange; a transverse wall across said channel, an opening from said channel near said transverse wall, into the retort; means for introducing hydrocarbon fluids into said annular channel; a cup situated within an air-chamber beneath the retort; an air-mixing member consisting of a ring having members extending inwardly between the ignition-holes in the retort; a vapor-generator situated within the heat zone of the burner, consisting of a hollow chamber having inlet and outlet openings communicating with the burner and base of supply respectively substantially as described.

2. In a hydrocarbon-burner the combination of a retort, having an annular channel formed around its upper edge, an opening in said channel communicating with the retort; an outwardly-extending annular flange near the top of the retort; ignition-holes near the bottom of the retort; means for directing a draft of air into contact with the flame of the burner substantially as described.

3. A retort for hydrocarbon-burners, consisting of an inverted-cone-shaped chamber with upwardly-extending, overhanging walls, having an outwardly extending annular flange near the top thereof; an annular channel formed around the top of the retort, a transversewall in said channel; means for introducing hydrocarbon fluids into the chan nel on one side of the transverse wall therein; and providing for the escape of the said hydrocarbon fluids into the retort on the opposite side of said transverse wall; ignition-holes near the bottom of said retort substantially as described.

4. In a hydrocarbon-burner, a retort hav-- ing a side wall, a downwardly extending flange upon said wall, there being provided a channel for the fluid above the apex of the opening between said wall and said flange, and a burner below said flange whereby the heat is directed between said wall and said flange, there being provided a passage for the fluid between said channel and said burner; substantially as described.

5. In a hydrocarbon-burner, a retort having an outwardly-flaring Wall, a downwardlyextending flange upon said wall, there being provided a channel for the fluid above the apex of the opening between said wall and said flange, and a burner below said flange whereby the heat is directed between said wall and said flange, there being provided a passage for the fluid between said channel and said burner; substantially as described.

6. In a hydrocarbon-burner, a supporting base member having an opening through the top thereof, a retort supported upon said base member and extending through said opening, said retort having flame-openings in its side walls, and a member resting upon said base member and having inwardly-extending fingers which lie adjacent said flame-openings for breaking up air flowing t0 the flame; substantially as described.

In testimony whereof I have hereunto set my hand this 28th day of July, 1900.
